NBIS — Nebius Group N.V.

Current Thesis

The financing overhang resolved on 2026-08-24, and it resolved at the maximum. Nebius announced the closing of its two-series convertible offering with aggregate gross proceeds of approximately $5.75B, after the initial purchasers exercised in full their options on an additional $450M of the 0.50% notes due 2030-02-15 and an additional $300M of the 4.50% notes due 2034-02-15. That option had been open into early September; demand did not stop at the priced $5.0B. Alongside the closing, $800M of existing paper — $400M of 2.00% notes due 2029 and $400M of 3.00% notes due 2031 — was exchanged for roughly 15.8 million Class A ordinary shares. The 2026-08-20 pricing release estimated net proceeds of up to approximately $5.68B on full exercise.

The narrative leg on offer stays an operating one: contracted megawatts converting into recognised ARR at prices management put on the record on the 2026-08-12 call, with the 2027 build now funded without a common-equity offering. What the last seven sessions changed is the price the market pays for it. The shares closed $210.91 on 2026-08-24, against $219.13 on 8/21, $223.90 on 8/19 and $277.68 on 8/14 — 26.4% below the 52-week high of $286.69, with RSI(14) at 46.5 and a three-month price change of +1.4%. The operating numbers compounded through the quarter; the quote round-tripped it.

The narrative is maturing, dated 2026-08-24. The operating leg still compounds on filed numbers (ARR $3.0B at 6/30 from $1.92B at 3/31). Attention is already mainstream — NBIS ranked among the five most-discussed names on X and r/WallStreetBets for the week of 2026-08-10 to 08-14 and drew a retail-facing "Stock of the Day" piece on 8/20. And the marginal supplier of stock is now the issuer plus the hedge book standing behind approximately $5.75B of new paper and the 15.8M newly issued Class A shares. D.A. Davidson's 8/18 move — target raised to $250 from $175, rating held at Neutral — is a number following price rather than a rating change.

Bullish and bearish views on Nebius Group N.V.

The model's bull view on Nebius Group N.V. (NBIS), in brief: Q2 2026 (Form 6-K, 2026-08-12): revenue $582.3M, +454% YoY and +46% QoQ; Nebius AI cloud $574.9M of that; adjusted EBITDA $236M at a 41% margin against −$21M a year earlier; adjusted EPS −$0.12 versus −$0.62 consensus. The bear view: FY2026 revenue guidance was affirmed at $3.0–3.4B on 8/12 against a $3.392B consensus estimate — the top of the range roughly meets the estimate, and it was not raised alongside a 46% sequential quarter. Both cases follow in full.

Bull Case

• Q2 2026 (Form 6-K, 2026-08-12): revenue $582.3M, +454% YoY and +46% QoQ; Nebius AI cloud $574.9M of that; adjusted EBITDA $236M at a 41% margin against −$21M a year earlier; adjusted EPS −$0.12 versus −$0.62 consensus.
• ARR $3.0B at 6/30, from $1.92B at 3/31 and $1.25B at end-2025, against an exit-2026 guide of $7–9B. The implied sequential path is arithmetic, without a required Q4 step-change.
• Unit pricing on the record (2026-08-12 call): $40–50M per MW on short-term deals, $20–25M/MW on mid-term contracts with upfront payments covering 50–60% of associated capex, and an inaugural capacity auction clearing 15% above the highest price Nebius had previously charged. CEO Arkady Volozh said on that call the company could sell its entire 2027 capacity today at those terms.
• Capacity secured with a named landlord: the 2026-08-13 lease with Vantage Data Centers for high-density NVIDIA-powered capacity at the CWL1 campus in Newport, Wales, described as the first announced commercial capacity commitment in the South Wales AI Growth Zone.
• The dilution boundary is a filed number. Conversion prices are ~$313.46 (2030s, a 40.0% premium to the 2026-08-19 close of $223.90) and ~$324.65 (2034s, 45.0%); both series accrete above par — to 110% and 125% of principal — lifting effective conversion prices to ~$344.81 and ~$405.82, well above the 8/24 close of $210.91.
• NVIDIA disclosed a 9.3% stake on 2026-07-20. The allocated-silicon supplier is also an owner of the equity.

Bear Case

• FY2026 revenue guidance was affirmed at $3.0–3.4B on 8/12 against a $3.392B consensus estimate — the top of the range roughly meets the estimate, and it was not raised alongside a 46% sequential quarter.
• Issuance into strength is the observable: approximately $5.75B of convertible paper struck off the $223.90 reference close of 8/19, plus ~15.8M Class A shares delivered in the exchange, all within nine sessions of the 8/14 close of $277.68.
• Vineland permitting sits inside the affirmed FY2026 guide. Two municipal stop-construction orders (2026-08-06 and 2026-08-10) carry $2,000 per violation per day.
• Michael Burry disclosed adding NBIS, MU and ORCL shorts on 2026-08-12 — the compute-oversupply argument aimed directly at the per-MW pricing above.
• Benzinga reported on 2026-08-21 that Citadel sold roughly 80% of its rescued AI book in about $4B of block trades, naming NBIS alongside MU.
• The $27B Meta headline is $12B of firm dedicated capacity plus up to $15B Meta takes only if Nebius fails to sell it elsewhere. Deliveries begin early 2027 and none of it sits in reported ARR.
• Sector beta has repeatedly overwhelmed company execution: SOXX fell 21.2% in July, its worst month since December 2002, and NBIS moved with CRWV, IREN, HUT and GLXY through both legs.

Setup & Price Structure

The reference closes through the drawdown window run in one direction — $277.68 (8/14), $223.90 (8/19), $219.13 (8/21), $210.91 (8/24) — and no higher close has printed in that sequence to define a base. RSI(14) at 46.5 sits mid-range, so the 8/20 retail piece calling the name oversold at support was published ahead of two further lower closes.

Overhead: the $223.90 close of 8/19 is the level the convertible was struck against, and the stock no longer trades there. Above that, $277.68 (8/14) and the $286.69 52-week high. Beneath: the 8/11 close of $193.23 is the floor of the post-Q2 range, and under it the 7/18 low of $164.31 is the last shelf below the June breakout. The covering happened into the run to $286.69. Nebius has been a Nasdaq-100 constituent since the 2026-06-22 rebalance, so index-tracking flow moves the shares independently of company news. There is no Form 4 stream to read: as a foreign private issuer Nebius is exempt from Section 16. The issuance evidence is therefore corporate, not personal — approximately $5.75B of paper and ~15.8M new shares, both live in the market from 2026-08-24.

Catalyst Calendar (next 30 days)

• 2026-08-26 — NVIDIA Q2 FY2027 results (quarter ended 2026-07-26), after the close. Supplier and 9.3% holder; its data-centre guide resets the whole AI-compute complex and Nebius does not control the outcome.
• ~2026-08-26 (est.) — FINRA semi-monthly short interest, 2026-08-14 settlement. Spans the run to the $286.69 high: covering off 25.6% of float, or fresh shorting into strength.
• ~2026-09-10 (est.) — FINRA short interest, 2026-08-31 settlement. First read fully spanning convertible pricing and closing. Short interest rising with a stable price is consistent with delta hedging; rising with a falling price is not.
• ~2026-09-10 (est.) — August 2026 CPI. The 8/18 decline across AI cloud names was attributed to inflation and yields; Nebius revenue is weighted to capacity delivering 2027–2031, so the discount rate is a live input.
• ~2026-11 (est.) — Q3 2026 results on Form 6-K. First update to the $7–9B exit-2026 ARR guide.

The 13-day initial-purchasers option that sat in the prior calendar for ~2026-09-06 is resolved — exercised in full at the 8/24 closing — and drops off.

Elapsed catalysts

• 2026-08-25 — Annual General Meeting. Per the convocation summarised by TipRanks, the agenda covers the 2025 accounts, discharge of directors, auditor appointment, board reappointment, and authorisations over share issuance, buybacks and cancellation of Class C shares. The issuance authorisation sets the headroom for any future equity. (passed 1d ago)

What Would Change Our Mind

The August range is what has to hold. The 8/11 close of $193.23 is the floor of the post-Q2 range, and nothing since 8/14 has printed a higher close to build a base off. A weekly close below $193 breaks that range and reopens the 7/18 low of $164.31, and would read as the market repricing approximately $5.75B of new paper and 15.8M new shares rather than absorbing them.

Second, the theme flipping to saturated: the ~2026-09-10 FINRA print showing short interest rising while the price falls, together with no new contract or ARR headline between now and the November Q3 report, would say the bid is coming only from index flow and hedging.

Third, the operating claim itself. The exit-2026 ARR guide of $7–9B narrowed downward at the Q3 6-K, or FY2026 revenue tracking toward the low end of the affirmed $3.0–3.4B, breaks the compounding argument independent of any price level. A subsequent capacity auction clearing below the prior high price would do the same to the $40–50M/MW disclosure.

And the 2026-08-26 NVIDIA print is a binary Nebius does not control. A data-centre guide below consensus and a gap lower alongside CRWV and IREN on no Nebius-specific news would be sector repricing, not a company event — the distinction matters for how the level above is read.

Correlation Notes

• NVDA is the single largest one-day driver into 8/26 — supplier of allocated silicon and a 9.3% holder since the 7/20 disclosure.
• Neocloud complex: NBIS has moved with CRWV, IREN, HUT and GLXY through both the July drawdown and the August rebound. The Futurum Group ledger put IREN at $40M/MW contracted revenue on 8/18, now the public comp against Nebius's disclosed $40–50M/MW short-term pricing.
• Semis beta: SOXX fell 21.2% in July, its worst month since December 2002.
• Rates: the 8/18 decline across AI cloud names was attributed to inflation and yields; revenue weighted to 2027–2031 capacity makes the multiple discount-rate sensitive.
• Index flow: Nasdaq-100 membership since 2026-06-22 adds a passive bid and passive supply unrelated to company news.
• Convert arb: the 8/24 closing establishes a delta-hedged short against approximately $5.75B of paper, which mechanically sells strength and buys weakness and will appear in the FINRA short-interest series without directional intent behind it.
